Scalar multiplication

In mathematics, scalar multiplication is one of the basic operations defining a vector space in linear algebra (or more generally, a module in abstract algebra). In common geometrical contexts, scalar multiplication of a real Euclidean vector by a positive real number multiplies the magnitude of the vector—without changing its direction. The term "scalar" itself derives from this usage: a scalar is that which scales vectors. Scalar multiplication is the multiplication of a vector by a scalar (where the product is a vector), and is to be distinguished from inner product of two vectors (where the product is a scalar). (Wikipedia).

Scalar Multiplication with Vectors

Hi All Happy Monday 18th June 2020. Today's video is a short video on multiplying numbers with vectors I.e scalar Multiplication with vectors. The idea is we multiply the number by the vector. We stay consistent with the signs and that's all we do. If we have a negative multipled by a po
